The skuas () are a group of predatory seabirds with seven species forming the genus Stercorarius, the only genus in the family Stercorariidae. The three smaller skuas, the Arctic skua, the long-tailed skua, and the pomarine skua, are called jaegers in North American English.

The English word "skua" comes from the Faroese name for the great skua, skúgvur [ˈskɪkvʊɹ], with the island of Skúvoy renowned for its colony of that bird. The general Faroese term for skuas is kjógvi [ˈtʃɛkvɪ]. The word "jaeger" or Jäger is German for "hunter". The genus name Stercorarius is Latin and means "of dung"; the food disgorged by other birds when pursued by skuas was once thought to be excrement.

Skuas nest on the ground in temperate, Antarctic, and Arctic regions, and are long-distance migrants. They have even been sighted at the South Pole.
